Abstract: An embodiment of the present disclosure discloses an automatic temperature-sensing and heating camera module at least comprising a lens barrel, a first lens arranged at a front end of the lens barrel, a gland that cooperates with the front end of the lens barrel for locking the first lens on the lens barrel, and a heating sheet capable of heating the first lens, wherein a gland flange is arranged at a rear end of the gland, and the heating sheet is arranged in close contact with the gland flange. In the automatic temperature-sensing and heating camera module according to the embodiment of the present disclosure, the heating sheet is arranged in close contact with the gland flange, so heat is transferred to the first lens through the gland flange, which has the advantages of simple structure and good heating effect, and is conducive to miniaturize the whole module.

Abstract: A large-aperture, high-pixel optical system has six lenses arranged successively from its object side to its image side along its optic axis. The first lens has a convex surface facing the object side and a concave surface facing the image side; The third lens is biconcave; the second and fifth lenses are biconvex; the fourth and sixth lenses each have a concave surface facing the object side and a convex surface facing the image side. The fifth lens and the sixth lens form a combined lens and the optical system satisfies TTL/EFL?4.5. Also disclosed is a camera module using the system. The system and the module are mainly composed of six lenses. Since the number of lenses used is limited, the structure is simple.
